Champion's Wreath

Refinement has a chance to fail. Upon failure you will lose the catalyst Wreath but the one you're wearing will not be destroyed.

If the Champion's Wreath you're wearing is upgraded to +8, Frank will instead offer to exchange it for a Promethean Crown costume, which retains the EXP increase and, unlike the Wreath, is tradable. Wearing the Crown and Wreath simultaneously stacks the bonuses additively.
